Abstract: Firstly, the origin、water quality and quantity of beer wastewater were analyzed, then the methods of dealing with beer wastewater at present were compared and discussed. On the basis of investigating the treatment of Yingbo beer Group’s beer wastewater and according to the stronger bio-chemical and the higher density characteristics of beer wastewater, we choosed SBR to deal with the wastewater. The results of the experiment showed that SBR was a better method to deal with the beer wastewater, it had the characteristic of saving the total investment、easy management、and less energy cost. The technical parameters of SBR treating beer wastewater were also discussed.
